“…Drought stress affect negatively on anthesis, grain filling of maize associated with reduction of number seed/cob, 100 grain weight and ultimately grain yield. Increasing of cassava yield with biochar application has been shown by Islami et al (2011) and Mannan et al (2016) reported that biochar increased pod yield of soybean under saline stress. Foster et al (2016) observed biochar application increased maize yield semi arid conditions.…”

The present experiment was conducted to study the impact of rice husk biochar on growth, water relations and yield of maize (BARI Hybrid Bhutta- 9) under drought (60 and 40% of FC) conditions. Four doses of rice husk biochar @ 0, 5, 10 and 20 t/ha were applied as an amendment in soil before sowing of seeds. Results revealed that drought stress reduced plant height, relative water content and grain yield of maize. But rice husk biochar at different doses improved the above mentioned characters under drought conditions. Under 60% of FC, the highest plan height, leaf water content and yield were 196.67 cm, 79.86% and 89.75 g/plant, respectively when biochar was applied @ 20 t/ha but it was 173.33 cm, 78.32% and 84.57 g/plant, respectively under 40% of FC when biochar was applied at the same dose. It may be concluded that, rice husk biochar @ 20 t/ha showed the best result to promote growth, water relation traits and yield of maize under drought condition.

“…Biochar was produced from rice husk by pyrolysis in biochar stove developed by Mia et al (2015) and modified by Mannan et al (2016). The chemical properties of rice husk biochar were N 2.57%, P 0.21%, K 0.231%, Ca 1.024%, Mg 0.458%, S 0.339%, EC 1.325 mS/cm and 7.15 pH was recorded.…”

“…Similarly, the total height of D. barbatus decreased with increased water stress at once every 3 days watering frequency on this soil, even though its mean height did not decrease. Water stress results in depression of plant height (Nielsen and Nelson, 1998;Shenkut and Brick, 2003;Mannan et al 2016) especially in soils that easily become dry and hardened as it is the case for Leaf mold soil. Also, reduced soil moisture during the early seedling stage diminishes growth which in turn would result in a reduction of yield (Constable and Hern, 1978).…”

This study was carried out to determine the effect of various watering regimes in different soils on seed germination and seedling establishment for two species (Dianthus Barbatus and Lespedeza cyrtobotrya) The ratio of water used for watering was 16ml water/100g soil. Three watering frequencies (i.e. once daily; once every 2 days; once every 3 days) were applied for two soil types (Leaf mold soil and merchantable soil) for a period of 150 days. The differences in seed germination, seedling survival and seedling growth were monitored in all experimental units. A more regular watering frequency increases soil moisture, and vice versa. The results showed that watering frequency had significant effects on seed germination (p=0.008), number of plant leaves (p=0.05), with visible but statistically insignificant effects on mean plant height (p=0.19) and seedling survival (p=0.3) for two plant species. The total height of plant species also varied greatly within treatments. Positive correlations were recorded between germination rate with leaf number (r=0.79, p=0.0001); plant height with survival rate (r=0.65, p=0.001); plant height with leaf number (r=0.77, p=0.0001); survival rate with leaf number (r=0.66, p=0.0001) etc. Seed germination and aboveground heights of D. barbatus and L. cyrtobotrya decreased at the more regular watering frequency of once daily in both soils. On leaf mold soil, the total height and mean height of L. cyrtobotrya decreased with increased water stress at once every 3 days watering frequency. Also, the total height of D. barbatus decreased with increased water stress at once every 3 days watering frequency on this soil, even though its mean height did not decrease. In contrast on merchantable soil, the total height and mean height of L. cyrtobotrya increased with increased water stress at once every 3 days watering frequency, indicating that this plant is more resistant to stress on this soil. Whereas, the total height and mean height of D. barbatus decreased with increased water stress on this soil. On leaf mold soil, once every 2 days watering was the most suitable watering frequency for both species in terms of achieving best seed germination and seedling establishment. In contrast on merchantable soil, once every 3 days watering frequency was most suitable for L. cyrtobotrya, whereas both once every 2 days and once every 3 days watering frequencies were suitable for D. barbatus on this soil. The results suggest that using the required watering frequency and soil type is imperative to ensure sustainability in plant production and seedling establishment.

This chapter discussed on mitigating effects of rice husk biochar to the drought effect on maize ("BARI Hybrid Bhutta 9"). Four doses of rice husk biochar at 0, 5, 10, and 20 t/ha were applied in soil before sowing of seed. Drought treatments were maintained at 60% of field capacity and 40% of field capacity by watering every alternate day, and 80% of field capacity (control) was also maintained as wellwatered treatment. Plant growth and physiological parameters were studied at 6th leaf, 10th leaf, 14th leaf, tasseling stage, cob initiation stage, and maturity stage, and yield contributing parameters were studied after harvest. Soil physical and chemical properties were studied before sowing and after harvest of crop. Drought stress reduced plant morphological growth and affected physiology and yield of maize. Mitigation of drought stress in maize was well associated with the reduction of proline content, maintenance of water-related traits, exudation rate and enhanced chlorophyll content and SPAD value, as well as dry matter production. Rice husk biochar improved the growth and yield performance of maize under drought condition. Biochar application at 20 t/ha was the best treatment to improving drought tolerance in maize.
